HFS (R) Grade B GAGE Gauge Block Set

Inexpensive price, received in good condition in solid storage case. Gauge blocks seem adequate for general use in a professional machine shop.

I bought this set to use for my sine vise and sine bar when I do setups on my Bridgeport mill. This is an excellent gage block set for shop use.

Much like what every other reviewer says, they box they come in is garbage... Mine arrived in two pieces but after some wood glue and staples, it is feeling super solid again. The blocks are accurate to about .0002", with ±.0002" run out along the block... Pretty good for the price honestly!

It may be a bit of overkill for me, as I am woodworker. It was purchased to help with machine setups. Item arrived half way round the world (West Australia) in perfect condition. It may seem strange buying a Imperial Gage Block set to be used in a country which has been using the metric system for around 30 years, but, most tooling in the woodworking world is still entrenched in the imperial system. Router bits and saw blades almost without exception are all still imperial. The only exception I have found is in straight router bits, there is a good selection of metric and imperial.So, this set I am sure will serve me well.

I should of read the reviews before purchasing. The case was broken with it arrived. It is made of some cheap MDF material and the side had fallen off.The blocks look as expected and do wring together. I needed the blocks for a setup or I would of returned it and bought something better. I glued the side back on but I suspect I will be regluing all the pieces soon.

Great product and great price!

No issues.To calibrate my equipment

Cert says Grade Economy which is Grade B, as advertised, which has many sub grades. The worst or most forgiving sub grade for B is AS2. The cert has a number of deviations listed which exceed the allowable deviation for AS2. So this is not a grade economy or grade B set. Also measured the .100, .200,.300, .400, .500 and .600 blocks. What I measure and what the cert deviations says for these blocks do not match. Its a nice set but you have to create your own cert to know what size each block is at 68F.
